-The tests are isolated from the actual source code, because they are supposed to test the same interface that the action also uses.
-This means that the tests **must not** import anything from the source code or vice versa.
-
-### Run linting and type checking
-
-This project uses pylint and flake8 for linting / code style checking and mypy for static type checking.
-
-All tools are configured in the `pyproject.toml`.
-
-```bash
-# with poetry shell
-# working directory: repository root
-pylint get_release_version_action
-flake8 get_release_version_action
-mypy get_release_version_action

-pylint tests/e2e
